![]() ![]() Myth: Heartbeat as an indicator of sexĭo not avert your eyes during an ultrasound appointment out of fear that the speed of the fetus’s heartbeat will reveal its sex. However, there are studies that show that morning sickness is a predictor of a healthy pregnancy. Once you’ve conceived, you may have heard that your experience with morning sickness is a sex predictor. Myth: Morning sickness indicates it’s a boy Without an orgasm, the environment remains slightly acidic. After a woman has an orgasm, the vagina is more alkaline. This myth is predicated on the unproven theory that Y sperm are healthier and stronger in an alkaline environment and X sperm are more robust in an acidic one. There’s an unproven hypothesis about the timing of a woman’s orgasm and the kind of environment that results. And, if you love red meat, salty foods and potassium-rich foods, like bananas, it will not increase the odds that you’ll conceive a boy. So, if you eat a high sodium, high calcium diet along with eggs, yogurt and chocolate, do it because that’s what you like to eat, not because you want a girl. There’s a myth that eating alkaline foods prepares the female reproductive system to be more friendly to Y sperm and acidic foods make for a more X-friendly environment.ĭiet cannot dictate the sex of your child. When it takes longer to get there, only the girl sperm will make it to the waiting egg. The erroneous theory is as follows: Because X sperm are more robust, they will outlive the boy sperm on the collective sperms’ journey to the egg. This same theory suggests that if you want a girl, less deep penetration gives girl sperm a greater chance to get to the egg. The myth suggests that deeper penetration allows for boy sperm to get a running start, and reach the egg faster. Myth: Certain sexual positions will result in a girl and others will help you conceive a boy Specifically, this myth suggests that sex closer to ovulation will result in a boy because Y sperm (boy sperm) swim faster than X sperm (girl sperm), but X sperm are hardier. ![]() Like the previous myth, this concept is based on sperm speed and sperm hardiness, or robustness. This is not a fact, nor is there any scientific evidence to prove the hypothesis. Myth: When trying for a boy, have sex closer to ovulation When trying for a girl, plan further ahead Or, how much longer one can live than the other. That, in turn, means there’s no difference between how capable an X or Y sperm is at swimming, or even how much more robust one is. However, as popular as this hypothesis has become, numerous studies have shown that there is no shape or size differences between X and Y sperm. One from the 1960s suggests that sperm with Y chromosomes have less DNA, which allows them to swim faster in viscous liquids. While there have been many hypotheses dating back decades about why, none have been proven. That is especially advantageous to a Y chromosome, though it’s not clear yet why that is. That is, women who take longer to conceive may be more likely to have thicker cervical mucus. The authors of the study of more than 5,000 women suggests that, “More viscous cervical mucus reduces the chance of conception and increases the chance of male offspring.” Myth: The longer it takes you to get pregnant, the more likely it’s a boyĪ 2005 study suggests this is true. ![]() That’s because “gender” refers to a person’s identity, not necessarily their biology. While many expectant couples have gender reveal parties, the term is incorrect. But, before we get started, it’s important to note the difference between gender and sex. īelow, we’ve debunked the myths around guessing your baby’s sex. Yvonne Bohn, Allison Hill and Alane Park in an interview with NPR. If the sperm has a Y chromosome, it will be a boy, according to Drs. The bottom line is as follows: If the male’s sperm that fertilizes the female’s egg has an X chromosome, the baby will be a girl. The fact is, none of these old wives tails or medical gimmicks guarantee to help you determine the sex of your future child. And, of course, there’s a lot of murmuring about sexual positions - some are “better” at helping you conceive a boy, and some are better for a girl. There are some who say it’s all about whether the female has an orgasm and if it comes before or after the male’s orgasm.
